Approximately 70% of the U.S. population recycles. According to
a green survey of a random sample of 250 college students, 204 said
that they recycled. At α = 0.01, is there sufficient evidence to
conclude that the proportion of college students who recycle is
greater than 70%?
1, This is a (answer "left", "right", or
"two") tailed test.
2, The critical value equals .
3, the test value equals .
4, the p value equals .
5, By compare the test value with critical value, we (answer
"can" or "cannot") reject the null hypothesis.
6, Draw the conclusion. There is (answer "enough" or "not
enough") evidence to support the claim that the
proportion of college students who recycle is greater than 70%.
